The Kaplan Book says that there are 5 kingdoms but the Barron's AP Bio says there are 3 Kingdoms/Domains.. Can anyone help me out? What Im not understanding is the difference between kingdoms and domains, i guess.

DAT = 5 Kingdoms

It's quite normal to get confused about taxonomy since it's a classification system that's constantly changing. There are various classification systems ranging from a 2-kingdom system to a 5-kingdom system and different books (usually depending on when they were published) use different classification systems. The most recent one, I believe, is the 5 kingdom system, is comprised of the following kingdoms:


1-Monera (Prokaryotes)

2-Protista

3-Fungi

4-Plants

5-Animals

The 4-kingdom system considered Fungi as part of the plant kingdom [Correction: There's really no mention of Fungi in the 4-kingdom system, so I probably misspoke, when I said Fungi were considered part of the plants].
The 3-kingdom system considered Monera as part of the Protista kingdom.

Hope this helps!

Do you guys know where archea fall in place?
I was always curious 😛

This is actually false.

The most recent tree is composed of 3 domains and 4 kingdoms.

3 Domains:

Archaea, Eukarya, Eubacteria


Within the domain Eukarya, we have 4 kingdoms:

Animalia, Plantae, Fungi, Protista


*Monera is out like yesterday's garbage

The 4 kingdom system does not include fungi as part of the plant kingdom lol. Fungi and plants couldn't be more distantly related.

Remember.. Fungi have chitin -- an animal characteristic. Fungi are more closely related to animals than they are to plants.

The Monera were divided up amongst Archaea and Eubacteria after they got the boot from Eukarya.

You're going to quote wikipedia which is referencing decades-old phylogenies?

Get with the times..

Not Wikipedia

"Diversity of Life: Biological Organization and Relationship of Major Taxa (Six-Kingdom, Three-Domain System) – plantae, animalia, protista, fungi, eubacteria (bacteria), archae, etc."

I know in 2007, I think they said 5 Kingdom system.

I was going to memorize the version from Cliffs ap biology I guess? I think it does what the ada lists.

This is the correct system. When I say four kingdoms, I'm specifically referring to those within Eukarya.

Commonly, you will see the Domains Archaea and Eubacteria called kingdoms in reference to a 3 domain, six kingdom system. I don't like calling them kingdoms and I'm not sure who started this or why it continues but it does irritate me. Technically they are not kingdoms at all.. only domains. They both have their own independent kingdoms, none of which are called Archaea or Eubacteria. I wish I knew what the justification was in calling them kingdoms.
